Check Digit Verification of cas no

The CAS Registry Mumber 183435-01-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,4,3 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 183435-01:
(8*1)+(7*8)+(6*3)+(5*4)+(4*3)+(3*5)+(2*0)+(1*1)=130
130 % 10 = 0
So 183435-01-0 is a valid CAS Registry Number.

Stereospecific syntheses of 5-alkyl-3-ethoxy-2-((phenylchalcogeno)methylene)tetrahydrofurans

Yoshimatsu, Mitsuhiro,Naito, Motoyo,Shimizu, Hiroshi,Muraoka, Osamu,Tanabe, Genzoh,Kataoka, Tadashi

, p. 8200 - 8206 (1996)

2-Ethoxy-4-(phenylchalcogeno)but-3-ynyl ketones 1-10 were reduced with LiBH4 in Et2O diastereoselectively to give 5-(phenylchalcogeno)pent-4-yn-1-ols 11-20. Treatment of the phenylchalcogen-substituted alkynyl alcohols 11-20 with t-BuOK in t-BuOH provided useful (Z)-2-((phenylchalcogeno)methylene)tetrahydrofurans 21-31 stereoselectively.
