Check Digit Verification of cas no

The CAS Registry Mumber 20220-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,2 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20220-77:
(7*2)+(6*0)+(5*2)+(4*2)+(3*0)+(2*7)+(1*7)=53
53 % 10 = 3
So 20220-77-3 is a valid CAS Registry Number.

A facile method for the preparation of carbodiimides from thioureas and (Boc)2O

Wu, He,Sun, Yan-Fang,Zhang, Chen,Miao, Chun-Bao,Yang, Hai-Tao

, p. 739 - 742 (2018/01/27)

A concise method for the preparation of carbodiimides from thioureas using di-tert-butyl dicarbonate [(Boc)2O] as the dehydrosulfurizative reagent has been developed. Using DMAP as the catalyst, a variety of symmetric and asymmetric 1,3-diaryl thioureas were converted into the corresponding carbodiimides efficiently in a short time.

A greener synthetic protocol for the preparation of carbodiimide

Ali, Abdur Rezzak,Ghosh, Harisadhan,Patel, Bhisma K.

experimental part, p. 1019 - 1021 (2010/04/02)

A new and facile preparation of symmetrical and unsymmetrical 1,3-diaryl and aryl-alkyl carbodiimides via a dehydrosulfurisation of their corresponding thioureas is described. Herein, the classical method of oxidative desulfurisation of thiourea to carbodiimide involving toxic heavy metal oxides (HgO) has been replaced with an easily available, cost-effective and environmentally benign reagent, iodine. Simple reaction conditions, easy purification of the products and high yields are important attributes of the present methodology and perhaps the best alternative from a green chemistry perspective. The only limitation to this method however, is in the preparation of 1,3-dialkyl substituted carbodiimide.
