Check Digit Verification of cas no

The CAS Registry Mumber 1213263-15-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,2,6 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1213263-15:
(9*1)+(8*2)+(7*1)+(6*3)+(5*2)+(4*6)+(3*3)+(2*1)+(1*5)=100
100 % 10 = 0
So 1213263-15-0 is a valid CAS Registry Number.

4-Aminothiourea prolinol tert-butyldiphenylsilyl ether: A chiral secondary amine-thiourea as organocatalyst for enantioselective anti-mannich reactions

Zhang, Hui,Chuan, Yongming,Li, Zhengyu,Peng, Yungui

supporting information; experimental part, p. 2288 - 2294 (2009/12/26)

anti-Selective Mannich reactions of N-p-methoxyphenyl (PMP)-protected α-iminoglyoxylate with unmodified aldehydes or ketones were effectively catalyzed by 4-aminothiourea prolinol tert-butyldiphenylsilyl ether. The reactions led to chiral β-amino carbonyl compounds in high yields (up to 94%), excellent diastereo- and enantioselectivities (up to 98% de and >99% ee). The study demonstrated for the first time that direct Mannich-type reactions of unmodified aldehydes or ketones to aiminoglyoxylate can be promoted by secondary amine-thiourea chiral organocatalyst.
