Check Digit Verification of cas no

The CAS Registry Mumber 1260145-36-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,1,4 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1260145-36:
(9*1)+(8*2)+(7*6)+(6*0)+(5*1)+(4*4)+(3*5)+(2*3)+(1*6)=115
115 % 10 = 5
So 1260145-36-5 is a valid CAS Registry Number.

Stereoselective approaches to the total synthesis of (6R,4′S, 6′R)-cryptofolione

Sabitha, Gowravaram,Reddy, S. Siva Sankara,Reddy, D. Vasudeva,Bhaskar, Vangala,Yadav, Jhillu S.

experimental part, p. 3453 - 3460 (2010/11/20)

Total syntheses of cryptofolione were accomplished by two different routes via a common intermediate that underwent a cross-metathesis (CM) reaction with a vinyl lactone. The intermediate was prepared by coupling of an acyl anion equivalent with a chiral allyl epoxide synthon, or by Prins cyclization of a trans-cinnamaldehyde with a chiral homoallylic alcohol. Goniothalamin was obtained as a cross-metathesis product of the diacetate and vinyl lactone. Georg Thieme Verlag Stuttgart.
